on your development PC/laptop: install dactest.py dependencies. You need python3 and then pip3 install requests colorama websocket-client
use ./dactest.py 192.168.0.117 (replace with your RPI IP)
it will use the RDK ASMS to list apps available from the cloud. Use "A" to start the procedure to add an app to ASMS
you will need to provide an id, name, version, the OCI image URL (see previous step) and a link to an icon to use. When prompted for "encryption" input "false". Unless you really want to test encrypted DAC apps. But for this feature there is a separate wiki page to read. Extra steps are needed for encryption. You can skip that for now and don't use encryption.
